Abstract

This document defines an IMAP4 extension, which gives an IMAP client
the ability to quickly resynchronize any previously opened mailbox as
part of the SELECT command, without the need for server-side state or
additional client round-trips. This extension also introduces a new
response that allows for a more compact representation of a list of
expunged messages (and always includes the Unique Identifiers (UIDs)
expunged). [STANDARDS-TRACK]
